本单元语法
用could 提出请求和征求许可
1.用could 提出请求:
常见的结构是“Could you(please)do sth?”,意为“(请)你做某事,好吗?”,是一种比较客气、有礼貌地提出请求的方式。如果同意对方的请求,可以用“OK.”或“No problem.”等来回答:如果不同意对方的请求,可以用“Sorry,I can't.”等来回答,并以委婉的方式来解释原因。
—Could you please open the door?
请你把门打开,好吗?
—Sure.当然可以。
Could you please sweep the floor?请你扫一下地,好吗?
---Could you take the dog for a walk?请你遛一下狗,好吗?
---Sorry, I can’t. I have too much homework to do.很抱歉,我不能。我还有很多的家庭作业要做。
2.用 could征求许可:
常见的结构是“Could I do sth?”,意为“我能/可以做某事吗?”。它的肯定回答和否定回答都不用 could,习惯上肯定回答用 may, can等,而否定回答用 can't 或 mustn't(语气重),有时也可避而不用。
—Could I smoke here?
我可以在这里吸烟吗?
—No, you can't, Look at the sign “No Smoking”!
不,你不能。看那个“禁止吸烟”的牌子!
